Title of Document: LUNG CANCER IN NEPAL: THE ROLE OF TRADITIONAL TOBACCO PRODUCTS AND COMBUSTION RELATED HOUSEHOLD AIR POLLUTION Greg A. Raspanti PhD 2016 Directed By: Amir Sapkota, PhD Maryland Institute for Applied Environmental Health The burden of chronic diseases such as cancer is increasing in low and middle income countries around the globe. Nepal, one of the world’s poorest countries, i...

in the last quarter of the century, a substantial amount of research work has been conducted on optimization of energy consumption by refrigeration systems and on proper design and construction of household refrigerator-freezers. the importance of such energy optimization schemes stems from the environmental impacts of freon (r-12) used as the working refrigerant in household refrigerator – fre...

BACKGROUND Alkoxyethanols (ethylene glycol alkyl ethers) are used as mixtures in a variety of industrial and household products. The aim of this study has been to evaluate the effects of 2-methoxyethanol (ME) and 2-ethoxyethanol (EE) on hematological changes induced by 2-butoxyethanol (BE) in rats. MATERIAL AND METHODS Experiments were performed on male Wistar rats treated subcutaneously with...

Recent past decades have witnessed remarkable advances in composites with potential applications in biomedical devices, aerospace, textiles, civil engineering, energy, electronic engineering, and household products. Thermoset polymer composites have further enhanced and broadened the area of applications of composites. In the present work epoxy-BMI toughened-silica hybrid (RHA/DGEBA-BMI) was pr...

Preservatives are chemicals that are added to products that contain an aqueous phase. These include cosmetics, topical medications, household products, foods, and industrial products such as glues, paints, dyes, metalworking fluids, and spin finishes. They are biocidal or biostatic, inhibiting the overgrowth of micro-organisms and protecting and retarding the chemical degradation of the product...

Carbonyl compounds (aldehydes and ketones) are suspected to be among the chemical compounds responsible for Sick Building Syndrome and Multiple Chemical Sensitivities. A headspace gas chromatography/mass spectrometry (GC/MS) analysis for these compounds was developed using derivatization of the compounds into volatile derivatives with o-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine (PFBOA). For GC...

Foreign body ingestion is a potentially serious clinical problem in children. We report a case of an 8-month-old infant who developed complete bowel obstruction requiring laparotomy due to ingestion of a superabsorbent polymer ball with advertised growth up to 400 times its original size. Most ingested foreign bodies that pass through the pylorus will make it safely through the gastrointestinal...

Accurate structural models are key to the optimization of the vibro-acoustic behaviour of panel-like structures. However, at the frequencies of relevance to the acoustic problem, the structural modes are very complex, requiring high-spatial-resolution measurements. The present paper discusses a vibration testing system based on pulsed-laser holographic electronic speckle pattern interferometry ...

The responses of young children to Denatonium Benzoate (Bitrex) were observed, in order to assess the potential of this bittering agent in the prevention of accidental poisoning. Thirty-three children aged 17-36 months were offered orange juice containing Bitrex (in a concentration of 10 parts per million). Of the 30 children who took some of this juice, only seven were willing to take more tha...

BACKGROUND Essential oils are fragrances extracted from plants. They have a smooth consistency and pleasant smell. Essential oils have been applied in aromatherapy, cosmetics, food and pharmaceutical products. The aim of the study was to analyze the composition of selected essential oils used in respiratory diseases. MATERIAL AND METHODS The qualitative analysis was performed by gas chromatog...
